Specification of Letters Patent.

Application filed May 26, 1911.

Patented Dec. 12, 1911. Serial No. 629,690. r

'appertains'to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The improved apparatus has for its object to facilitate the removal of the contents of' a box, chest, or tin in shops, for instance a tin of biscuits, sweets, etc., so that it shall not be necessary for this purpose to shift the tins from their support on to the shop counter or to employ supports of inconvenient height in order to be able to remove the contents from the tin with ease.

By means of the improved apparatus the tin is moved slightly and tilted somewhat forward, the lid is raised automatically during the tilting movement, the tin is held in the tilted position, and the lid is held in the opened position. In this position the contents can be removed wholly or partly with ease from the tin. By a gentle movement of the hand the tin is tilted back into its original position, the lid closing automatically.

Two embodiments of this invention are illustrated by way of example in the accompanying drawings in which: 8

Figures 1, 2 and 3 are three side elevations of one construction of the improved apparatus for facilitating the removal of the contents of a tin, showing the apparatus in three different positions. Fig. 4 is a horizontal section on the line A-B of Fig. 1. Fig. 5 is an elevation of the apparatus with a section through one edge of the tin- Figs. 6 and 7 are respectively an enlarged elevation and an enlarged plan of a portion of Figs. '1 and 4; Figs. 8 and 9 are respectively a side elevation and a plan of details, and Fig. 10 is a side elevation of a simplified construction of the'improved apparatus.

A guide bar 4' (Figs. 1, 6, 7 and 9) is provided for each tin on the bottom 1 of the hooks engage two oppositely situated side "edges of the lid 24 of the tin, which lid is pivoted on the axle m.

support or frame 3 containing the tins 2 and is fixed by means of screws 5. The right hand side part of a rectangular supporting and tilting-frame 7 (whose component parts are of L-section) rests on two feet 6 of the guide bar 4.

The left hand side part of the frame 7 is supported onthe bottom 1 of the frame 8 by means of a roller 8 fixed slightly in front of this side part, in such a manner that the roller shall not leave the bottom of the frame 3 during the tiltin movement. The frame 7 is intended to ho d the tin 2.

The guide bar 4 is formed at its forward end, with a slotted eye 9 (Figs. 5 to 9) carrying a ping12- on which a hand lever 10 having a gripping hole 11 is pivoted. An extension 13 of this lever extending at right angles therefrom carries a pin 14'and is connected by means of a connecting rod 15 to abar 16 parallel to the right hand side portion of the sliding frame 7 and attached thereto at its ends with interposed spacing pieces 17 and 18 (Fig. 8). I

A vertical fiat arm 19 (Figs. 1 and 4) is clamped between the rear spacing piece 18 and the rear end of the bar 16. A similar arm 20 is attached to the rear end of the The arms of the bent piece 22 have a certain amount of'resiliency relatively to each other so that the lid 24 'is gripped with certainty. The right hand arm of the bent piece 22 (Figs. '3 and 5) is connected by means of a connecting rod 25 to a rocking the guide 4 engages with a head 31 that prevents the arm 26 from slipping off the pin 30. p

The guide 4 (Figs. 2, 3 and 6) has an upwardly and forwardly inclined guide surface 32 for a pin 33 (Figs. 6 and 7) which extends across the space between the bar 16 and the right hand side part of the frame 7. The forward end of the guide surface 32 terminates in a recess 34 that serves as a rest for the pin 33. A tongue 35 extends from the guide 4 parallelly to the guide surface 32 so as to cover the upper portion of the rest 34.

A shoulder 36 on the guide A serves as a stop for the spacing piece 17 (Fig. 6) when the frame moves back. A projection 37 of the guide at, below which the bar 16 works, holds the latter in its lowest position and prevents the forward portion of the frame 7 with the tin 2 from rising.

The operation of the apparatus is as fol lows: To remove the contents wholly or partially from the tin 2, the hand lever 10 is rocked as indicated by the arrow I from the position shown in Fig. 1 into the position shown in Fig. 2, whereby the frame 7 with the tin 2 resting on it is pushed forward from the position shown in Fig. 1 into the position shown in Fig. 2, and is tilted slightly on the axis of the antifriction roller 8 by the rising movement of the pin 33 along the inclined guide surface 32 of the guide A. At the same time the arm 26 by sliding with its slot 28 over the stationary pin 30, is uprighted to a certain extent whereby the lid 24 of the tin 2 is partially opened. By the continued rotation of the handlever 10 in the direct-ion of the arrow I (Fig. 1), the pin 53 slides completely up along the upwardly inclined guide surface 32 of the guide 4, whereby the frame 7 with the tin 2 is tilted fully on the axis of the roller 8 into the position shown in Fig. 3. In this position the contents of the tin 2 are readily accessible. During the movement of the frame 7 and tin 2 from the position shown in Fig. 2 into the position shown in Fig. 3, the longitudinal slot 28, 29 by sliding over the pin 30 has caused the rocking arm 26 to swing into its highest position and has thus opened the lid 24 completely. The tongue 35 of the guide 4 prevents a premature tipping over of the frame 7 and tin 2. At the termination of the tilting movement the pin 33 drops into the rest 34 in the guide 4, and thus secures the frame 7 and tin 2 from tilting back and prevents them from tipping over. The frame 7 is held sufficiently against lateral shifting by the support given to it by the guide 4 which projects between the bar 16 and the frame 7. When the desired portion of the contents of the tin have been removed therefrom, the lever 10 is moved up again whereby the pin 33 is lifted out of the notch 3 1, the frame 7 with the tin 2 is first pushed back, and is then tilted back by the pin 33 sliding along the guide surface 32. This tilting back is effected with very little exertion because the weight of the contents of the tin aids the backward tilting movement. During the latter part of the backward movement of the frame 7 and tin, the pin 33 moves away from the guide surface 32, and this part of the backward movement of the frame takes place in a straight line on the feet 6 of the guide piece. In the backward tilting of the frame 7 and tin 2 the rocking arm 26 moves down again and thus closes the lid 24. Since only the lever 10 has to be operated, the contents of the tin can be removed very simply, easily and quickly.

In the simplified construction shown in Fig. 10, the lever 10 and the rod 15 are dispensed with, and the front part 38 of the frame is provided with a handle or grip 39 for drawing the frame 7 and the tin 2 forward, tilting them and returning them into their original positions. The most advantageous way as regards ease of manipulation is however to use the lever 10 and rod 15. The handle of grip 39 may have any desired form. The apparatus is also suitable for the tins of round or other shape.

In apparatus for facilitating the removal of the contents of a tin or other box, the combination .with a support, of a frame for holding and tilting the tin, a handlever pivoted to a fixed part, and connected to said frame, for moving said frame with the tin forward and backward, a fixed guide fixed to the support having an upwardly inclined guide surface, a pin on said frame movable along said guide surface for the purpose of tilting said frame forwardly, a rocking arm formed with an inclined slot, connected at one end to said frame and adapted to be connected at its other end to the lid of the tin, and a pin on the support engaging said inclined slot, whereby the lid of the tin can be opened and closed in a positive manner, as set forth.
